All I can say is what Ganja told me once - FTF is about the find, and so is associated to a person - you. However scuba cacher and night owl are about the cache itself. Project GC want to be able to present stats for everyone, so a bookmark list could work but someone would have to identify all the caches that go into it and keep it up to date. If you have a solution for this, let Ganja know. Iporefer to generate the badge based on the attributes, but ganja sited reliability issues there too (even though many of the other stats, such as number of large caches, are generated also generated from cache owner set cache parameters)
